I just would like some opinions on these. I think they're all the top series' of the brands and that's what I want since my ocz gold crapped out on me. (Don't know when or if it was always faulty, I just memtested it today after a system crash and they were both filled with errors. Also tried many different timings and voltages, oc'd and underclocked and just could not get them stable.)

For some reason I am leaning toward the mushkin. Again, I probably can't go wrong with any of these but just want some opinions. Depending, I may or may not OC.

I'll steer clear from Mushkin for me and my vote would go for Corsair, they have rock solid stability and performance - All of my PCs use those and they are used for work extensively on a daily basis, 7 days a week and on 24/7 and never failed me. I heard some people having had problems with mail-in rebates, but can't comment on that as I never had any issues with MIR in general, but never had to apply a MIR with COrsair so I can't tell but these are good performers. I don't know if this is a long shot but my old corsairs DDR-2 667 rated 4-4-4-12 were running 24/7 DDR-2 800 4-4-4-12 no problem for a long time - and still use it in an older PC and kicking, I've had issues with Mushkin and their not so good support, so my vote goes for Corsair all the way :)

Now am I on the right track here, is it better to get these kinds of performance rams over say $50 ram?
I definitely want some quality ram for serious gaming. I play a lot of games, a lot of the time, namely GTA IV and Crysis. Those are the most intensive of the bunch.
